Hey that's really great!  Thank A LOT!!!  I'll prolly go for it, I love Bryce but the visuals in VUE rock!  I'm on 10.6 with nVidia 9400 (MacBook) with 1920x1200 external.  I don't see a lot of GPU talk, though there does appear to be stuff in Infinite re. multi-pass shaders. Now:  Complete vs. Inifinte, that'll take some figurin'  (Oh fwiw, the most pleasant surprise this year is Cheetah3d)
